Unveiling the Reason for Syncope Associated With Cardiac Nodules.

Behcet's disease is a systemic immune-mediated vasculitis predominantly affecting males. Cardiac involvement, termed cardiac Behcet's disease, is rare but potentially fatal, often mimicking infective endocarditis. This case presented with syncope as the initial symptom, leading to the identification of a non-coronary aortic sinus nodule, suspected as the cause of intermittent complete atrioventricular block. After pacemaker implantation, no recurrent syncope occurred, and immunosuppressive therapy reduced nodule size. This case underscores the importance of maintaining a high suspicion for cardiac Behcet's disease, as early diagnosis and intervention can be lifesaving.
